Switching from about:home to a remote tab and back results in a gray screen. Likely fallout from the iframe panning stuff.
STR:

1.) Open about:home
2.) Open a link to a remote tab
3.) Switch back to the about:home tab

Results: Nothing is shown.
Assigning this to ben because he has a patch mostly in place. We think this likely has to do with local tabs setting their display port when active = false is called. That behavior isn't well defined, and we should probably just avoid doing it, as well as calling other methods like _updateCacheViewport on local tabs.

Switching to about:home can result in a gray screen

Looks good. Might be nice to throw something or add some debug spew for the local tab _updateCSSViewport and _updateCacheViewport pieces.

I'm not sure I'd do that. I have a patch that calls updateCSSViewport on any browser.
